To find the greatest common factor (GCF) of 39, 138, and 93, we first need to factorize each number. The factors of 39 are 1, 3, 13, and 39. The factors of 138 are 1, 2, 3, 6, 23, 46, 69, and 138. The factors of 93 are 1, 3, 31, and 93. The GCF of these three numbers is 3, as it is the largest number that divides all three numbers without leaving a remainder.
The numbers 93 and 108 do not have any common factors except the number 1, and so they are co-prime.
The greatest common factor of 64 , 93 = 1
The greatest common factor (GCF) of 62, 93, and 31 is 31. To find the GCF, you need to determine the factors of each number and identify the largest factor that is common to all three numbers. In this case, 31 is the only factor that all three numbers share, making it the greatest common factor.
The common factors of 69 and 93 are: 1, 3
